I see, well I dont know why but Logstash only listen on TCP connections over ZeroMQ. Moreover I tried following a simple example like this http://learning-0mq-with- pyzmq.readthedocs.org/en/latest/pyzmq/patterns/pair.html Not implementing the server myself but using logstash as server. It creates a very dummy connection over TCP. Hwever the link you gave me, explicitly says that PAIR is indicated for interproc, so I cannot really expect it to work I guess. By the way what I am trying to do is ------------ ---------- ------------- | APPLICATION | ---ZeroMQ----> | LOGSTASH | -> |ElasticSearch| ------------ ---------- ------------- Expecting ZeroMQ to implement some sort of reliable message shipping. ie. I want messages to be maintaned on a queue if the connection is no available or the remote machine crashed. Logstash is in a remote machine. Logstash only supports three communication types PAIR PUSH/PULL PUB/SUB Shall I try another type or shall I just give up this way? _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
